Abstract: ABSTRACT     A liquid polymeric composition comprises a suspension in an organic liquid of particulate water insoluble but water swellable polymer, the particles being less than 10 microns in size.   To reduce viscosity in water the swellable polymer may be a copolymer and/or a water soluble polymer may be included.  A composition of polymer particles that are swellable and contain both soluble and insoluble polymer can be made by inverse emulsion polymerisation.   An aqueous adhesive, that may be made by mixing this composition with water, comprises water swollen particulate polymer that may be a copolymer and that may be used with a dissolved polymer in order to reduce the viscosity.   Pregummed substrates, such as wallpaper, that can be rendered adhesive by contacting with water are obtained by applying the aqueous or non-aqueous composition to the substrate and drying it on the substrate.  Wallcovering can be stuck to a surface using the aqueous adhesive.

Abstract: ABSTRACT OF THE DISCLOSURE          In a digital servo control system, the duty cycle of a pulse width modulated signal for controlling a drive motor is determined by digital numbers representing phase and/or speed errors preset into a memory and circulating counter.  The cir-culating counter is driven by a clock signal which performs a number of cycles during each basic timing interval.  A pulse width modulated signal is initiated by a timing pulse and is terminated by each return to zero of the most significant digit of the circulating counter.  The time at which the most signifi-cant digit of the circulating counter returns to zero at the end of each of its cycles is determined by the number initially pre-set into it.  The memory is gated with the output of a four-bit counter, which increments at the same rate that the circulating counter cycles, to either lengthen each pulse width modulated signal by one clock cycle or not.  The number of times the pulse-width modulated signal is lengthened in a basic timing interval is proportional to the number preset into the memory.  The con-tents of the memory and the circulating counter are periodically changed to correspond to detected speed and/or phase errors to update the duty cycle of the pulse width modulated control sig-nal.

Abstract: S P E C I F I C A T I O N                  METHOD AND APPARATUS FOR AUTOMATICALLY LABELLING CONTAINERS                INVENTORS:  JOSEPH J. D'ANGELO                                  -and-JOSEPH J. D'ANGELO, JR.     ABSTRACT OF THE DISCLOSURE            Fully automated labor saving method and apparatus are provided for automatically labelling containers, including automatically supplying labels and applying them to the containers.  There is a label supply roll of a continuous web of preprinted labels which may also be pre-perforated for ease of separating one from another.  This web of preprinted labels is fed past a sensing device for sensing a registration mark on each passing label and an adhesive applicator for applying pressure-sensitive adhesive to each label.  A clamp temporarily clamps the web in response to signals from the sensor during the separation of the leading label from the web.  The leading edge of each label is fed to a label-engaging station with the adhesive-coated surface thereon positioned facing the container to which the label is to be applied.          Conveyor means continually transport a sequence of individual containers to be labelled to the label-engaging station where the respective container comes into contact with the adhesive coated end of the label.  Immediately, the container begins to be rolled in a labelling channel defined between a con-tinuously revolving belt having a friction surface thereon, which forms a moving wall of the channel, and an opposed stationary wall on the opposite side of the conveyor forming the other wall thereof for wrapping the label firmly around the container being rolled in this channel.  Pinch means are provided at the upstream end of the channel for driving the respective container transported by the conveyor means into firm contact with the adhesive-surface of the leading edge of a label while pressing the outside of the label against the continuously revolving belt, thereby commencing rolling the container within the conveyor channel.  After a predetermined amount of wrapping, the web is temporarily clamped and the label is separated from the web either by striking the con-tainer in the conveyor channel thereby separating the partially wrapped label from the web along the perforations or by cutting with a knife or with a hot wire.  Following the label separation the container continues to be rolled along within the conveyor channel for completing the wrapping of the label securely around the container.  In an alternative embodiment the label so wrapped may be heat sealed.
